Comet Hubble, formally designated C/1937 P1, is the first and only comet discovered by astronomer Edwin Hubble. The comet was already on its outbound flight when it was first spotted in August 1937 as a magnitude 13.5 object in the constellation Sagittarius.[1][5] It is the fourth comet discovered in 1937.[6]
